Extension forgets the settings after updating the browser

[seedofjoy]

Whenever you update your browser (or extension) it forgets settings.
This happens, because onInstalledevent fired on each browser or extension update.

Here docs: https://developer.chrome.com/extensions/runtime#event-onInstalled

Fired when the extension is first installed, when the extension is updated to a new version, and when Chrome is updated to a new version.
